BOAT DRIVING GEAR.

SPECIFICATION forming part of Letters Patent No. 643,490, dated February 13, 1900.

Application filed November 22 1899- Serial No. 737,910. (No model.)

To all whom it may concern:

Be it known that 1, JOHN A. FREUND, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Boat Driving-Gear, of which the followin gis afull,clear, and exact description.

The purpose of this invention is to provide an eifective means for manually driving screw and other propellers in marine vessels, particularly in small boats.

This specification is the disclosure of one form of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the Views.

Figure 1 is a plan view of the invention applied. Fig. 2 is a longitudinal section of the same. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4 is a fragmentary side View of a modified form of the invention adapting it to use by a plurality of persons, and Fig. 5 is a detail view showing one of the hand-levers of the invention.

The invention is applicable to a boat of any construction. As here shown, I have fastened in the boat a thwart 6, beneath which is rigidly mounted a frame-bar 7, running rearward and fastened to a transom S in the stern of the boat. On this frame-bar 7 is mounted a large bevel-gear 9, connected with a link 10, which extends forward beneath the thwart 6 and is connected at its front end to the transversely-bent arms 11 of levers 11, which levers are fulcrumed, respectively, at the sides of the boat forward of the thwart 6 and have their arms 11 extended inward and downward in proper position to be connected with the link 10, as explained. Each lever 11 has an extension or handle piece 11 pivoted thereto and provided with a slidable sleeve 11, which when thrown to the position shown in Figs. 1 and 2 causes the extension 11 to be held rigid on the lever 11, thus enabling the lever to be rocked to drive the wheel 9 through the medium of the link 10. WVhen the sleeve 11 is thrown to the position shown in Fig. 5, the handle portion or extension 11 of the lever 11 may be thrown downward below the gunwale of the boat in folded position. This is the position which the parts occupy when the driving-gear is not in use.

A bracket 12 is fastened at the bottom of the boat aft of the wheel 9 to carry the propeller-shaft 14, which is driven by means of a pinion 15, meshing with the gear 9, and which carries at its outer end the propeller 15 of any desired construction. By this arrangement upon the working of the lovers 11 the wheel 9 may be driven and the shaft 14 caused to turn, thus driving the propeller.

It is clear that according to the direction in which the levers 11 are operated the boat will be propelled forward or backward. I have provided means for holding the gear to prevent its backward movement when it is desired to drive the boat ahead and also for holding the gear to prevent its forward movement when it is desired to drive the boat astern. This gear comprises an elbow-lever 16, forming two pawls. The elbow-lever is fulcrumed on the frame-bar 7 and may, if desired, be provided with springs 17, tending to hold it in an intermediate position, and thus enable its quick action, as will be hereinafter explained. Ratchet-like lugs 18 are formed on the wheel 9 in position to be engaged by the arms of the elbow-lever 16. The elbow-lever has two chains 19 attached thereto respectively at opposite sides of its fulcrum,

and these chains are attached to a hand-lever 20 at opposite sides of the fulcrum of the same, the hand-lever being pivoted on a lateral extension of the frame-bar 7 and provided with a hand-pawl 21, working with a quadrant 22. The pawl and quadrant enable the lever 20 to be held in the position shown in Fig. 2 or in a position forward of that shown, as will be understood. When the elbow-lever 16 is thrown to the position indicated in Fig. 2, the

wheel 9 will be permitted to turn in the direction of the arrow shown in such figure to drive the propeller ahead, but it will be prevented from turning in the direction opposite that indicated by the arrow. By shifting the lever 16 these conditions will be reversed, as will be readily understood.

The person operating the boat should grasp the hand levers or extensions 11 to propel the boat, and such persons hands being thus occupied I have provided foot-operated devices for steering the boat. These devices comprise pedals 23, sliding in guides 24, attached to the boat and connected with chains 25, which are led aft over sheaves or rollers 26, as shown, and attached to the tiller-arms 27 of a rudder 28, which may be constructed and hung in any desired manner. Theoperator may thus be seated on the thwart 6 and propel the boat, using his hands for this purpose, and may steer the boat with his feet. This gear furnishes a convenient and easy means for propelling small boats, and by this means the power expended will be applied in the most advantageous manner possible, thus driving the boat ahead more rapidly than by the use of oars and the like.

The modification shown in Fig. el consists simply in duplicating the levers 11, enabling a plurality of persons to be engaged in working the boat. These levers 11 are provided with links 31, connecting them with a sliding bar 30, which is held to slide in a guide The bar 30 is connected with a link or connecting-rod 10, which corresponds with the link 10 before described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 7 1. In a boat driving-gear, the combination of a gear-wheel, means for imparting movement thereto, an elbow-lever forming a double pawl, pivoted adjacent to the wheel and movable to alternately engage its arms therewith, for the purpose specified, means for operating the elbow-lever, and devices driven by the gear-wheel and having connection with the propeller, to drive the same.

2. In a boat driving-gear, the combination of a wheel forming part of the gear and provided with two oppositely-disposed ratchetlike lugs, a double pawl mounted adjacent to the wheel and movable to alternately engage its arms therewith, the pawl working with the said lugs of the wheel, and means for shifting the double pawl.

3. In a boat driving-gear, the combination of a wheel forming part of the gear, and an elbow-lever forming a double pawl, pivoted adjacent to the wheel and capable of having its arms alternately engaged therewith to 0011- trol the movement of the wheel.

4C. In a boat driving-gear, the combination of a gear for imparting movement to the propeller-shaft, a connecting-rod attached to the gear to drive the same, and two hand-levers fulcrumed respectively on the sides of the boat and projecting upward above the same, each lever having its lower arm bent transversely and extended inward and downward to the end of the connecting-rod, to which rod such arms of the levers are pivotally attached.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN A. FREUND.
